TAMPA — A detention deputy accused of pointing a gun at a man in what authorities described as a road rage incident was expected to officially leave the Hillsborough County Sheriff's Office within a few days, officials said Wednesday.

An administrative termination process was under way Wednesday morning for Deputy Reginald J. Migues, sheriff's spokesman Larry McKinnon said. Separation of employment paperwork was awaiting final approval at the end of the day Wednesday, he said.

Migues, who has worked as a detention deputy at the Falkenburg Road Jail for 11 years, has no disciplinary history, officials said. On Tuesday, he was suspended without pay following his arrest on a charge of aggravated assault with a firearm. He was later released on $2,000 bail.

When approached outside his Tampa home Wednesday morning, Migues said he needed to take his wife to a doctor's appointment and offered no comment on the matter.

A day earlier, Migues was off-duty and driving with his wife near Williams Road and U.S. 92 in Seffner when another car approached from behind, according to sheriff's officials. The driver of the other car, Arthur Langley, 41, tried to pass Migues a few times, deputies said.

The two pulled over in a parking lot at 5520 Carmack Road. Migues got out of his car and approached Langley's car, deputies said. Langley started to get out as Migues brandished a .40-caliber Glock handgun, sheriff's officials said. Migues chambered a round and pointed the weapon at Langley, deputies said.

Langley got back in the car, closed the door and called 911 from a cellphone, officials said. Migues then walked back to his own car.

"There was nothing to indicate that there was any justification for his behavior," McKinnon said. "It's unfortunate. It's a very serious error."

Migues has a clean driving record and no other arrests in Florida, state records show.

Langley has a history of traffic violations, including a DUI conviction in 2008 and multiple citations for driving with a suspended license, state records show. He has also been to jail a few times, most recently in 2010 on a drug paraphernalia charge. There is no indication that the two men had previously encountered each other, officials said.

Langley did not return calls Wednesday for comment.
